To @ZZ w32/0m, it romy conceive.-

Be it known that I, JACOB CALVIN SMITH, u. citizen of the United States,and a resident of Luling, in the county of Caldwell and Sts-te of Texas,beve invented certain new and useful Improvements in Automatic Cer andAir-Broke Couplings, of which the following speciiicetion5x teken inconnection with the accompanying drawings, is e full, clear, and

ro exact description, such as will enable those skilled in the nrt toinsite and use the seine.

The object of my improvements is to provide n simple and effectivecombination coup ler for the cnrs und the eir'brnke pipes, which couplerwill be automatically operated by the bumping together of the cnrs lundWill obviute the necessity of en attendent.

To this end my invention consists essentinlly of automatic couplingdevices for the zo eers und einbrnlie pipes, which devices are connectedtogether by e. suitable system of levers so as to be automaticallyoperated by the bumping together of tlie cors. The carcoupling devicecomprises tbe ordinary drew z5 heed provided with e. sliding yokeadapted to cover tbe pin bolo end support the pin in elevated position,longitudinally movable bumper rods secured to the sliding yoke undadopted to move it from under the pin so as 3o to allow the seine todrop into locked posi-` tion, suitable operating levers for raising thepin und uucoupling the cer, and springs for returning illepin-supporting yoke under tbe end of tbe pin for supporting it in raisedpo- 3 5 sition. The coupling device for the air-brake pipes comprises nsectional coupling box lieving nir-tight connections with the train pipeof the sir-breites, n pipe section adapted to be automatically engagedby the coupling 4o box, und suitable levers connecting the movnble jewor section of the coupling box to the pin-operating levers. Andmyinvention con siste of other feet-uros of novelty, all of which willfirst be described with reference to the accompanying drawings nud thenovelty perticulerly pointed out in the claims.

ln seid drewingsz-Figure l is e. side eleve.- tion of portions of tworailway cnrs embodying my improvements, the device being in 5o coupledposition on one of the cnrs and in Serin-l No. 328,347. (No model.)

uncoupled position on the other cer, and the curs being represented inthe ect of coupling. Fig. 2 is an end view of one of the curs showingthe devices in coupled position. Fig. 3 is en end sectional vievr takenon the line 313, of Fig. 5. Fig. 4: is an enlarged deteil eleve.- tionot' tbe section ot coupling pipe, one end of tbe seine being broken awayto show the internal structure. Fig. 5 is nu enlarged deteil planelevation of the coupling device, the operating rods being shown insection. Fig. 6 is e. detail perspective view representing the ineensfor holding the operating levers in raised position.

1, l, is any ordinary construction of cars provided at their ends Withtbe customary drow-heads 2, 2.

3 is the ordinary coupling link, end 4 is the common construction ofcoupling pin which is adopted to slide vertically und rest in the pinopening which extends through the drewbend.

5 is e right-angled pin lifting erin having en opening 6 through itsforward enlarged end in which the pin 4 is sented.

7 is e set screw passing through a. suite-ble screw-threaded perforationin the pin lifter 5 and engaging the pin e so es to hold it securelytherein.

S is aJ vertically moving rod formed with e. bifurceted lower end E)which is pivotelly nttaclied to tbe vertical extension. of the pinlifter5, in order io allow for the longitudinal movement of the drew-bend whenthe pin is in coupled position. The rod 8 pessestlirougli suitableopenings in brackets l0 which are formed integral to the bese plete llwhich is secured to the front end of the cnr l es clearly shown in thedrawings.

l2 is n strong spiral spring surrounding the rod 8 and engaging et itsupper end the upper bracket lO end et its lower end the coller i3secured to the rod 8. The tendency of the spring l2 is to force the rod8 (carrying the pin-lifter und pin), downwardly. Projecting from the csrl, is en upright support 14 to which is pivoted the operating lever l5formed et one end with the bundle 16 and et the other end with the sloti7. The slotted end of the lever l5 is pivoted to the upper cud of theISO rod S as shown in the drawings, so that the said rod can be raisedvertically by said lever against the action of the spring 12.

18 is a tongue pivoted to the upper edge of the operating lever 15 andadapted to be moved to one side so as to engage the serrations 19 formedon the inner edge of the sup port 14, and hold the lever 15 and rod S inraised position so that the pin will not drop into coupled position.

In order to support the coupling pin in raised position, andautomatically drop it into engagement with the link at the proper time,I provide the following mechanism:-2O is a horizontally sliding yokeformed with the horizontal plate 21 adapted to rest on top of thedraw-head, and vertical plates or arms 22 embracing the sides of thedraw-head, and forming guides for the yoke in its horizontalreciprocation on the draw-head. 23 are sliding rods supported in theperforated ears 23u, and the perforated flange of the draw-head, andpassing' through and secured in eyes 24 formed on the lower ends of theplates 22 of the yoke. 25 are spiral springs surrounding the rods 23 andengaging at their inner ends the ears 23 of the draw-head and at theirouter ends the eyes 24 of the yoke, so as to hold the rods 23 and theyoke 2O normally in their outer positions. On the outer ends of the rods23 I form the customary bumper plates 2G, the rods 23 serving the doublepurpose of bumpers and means for actuating the yoke. lVhen the yoke isin its normal outer position, as shown on the right hand car of Fig. 1,the plate 21 thereof is directly over the pin-hole of the draw-head, sothat the end of the pin 4 cannot enter the pinhole, but will rest on topof the yoke and be supported thereby. It will also be observed that whenthe rods 23 are forced rearwardly against the action of the springs 25,the yoke 2O will also be carried to the rear and the plate 21 will beremoved from under the end of the coupling pin and allow the same todrop or be forced into position by the spring 12.

In combination with the above-described automatic car-coupler, I employan automatic coupling device for coupling the train pipes of thecustomary air-brake systems. This air-brake coupling device consists ofthe following mechanismz-Seeured to one side of the draw-head is theupper half or section 27 of the air tight coupling box, which has anair-tight connection, through which the coupling section 29, with thetrain pipe 28, which extends along under the car in the customarymanner. 30 is the lower movable section of the coupling box formed withthe rearwardly extending ear 31, which is pivotally connected to theextension of the upper section, both sections, when closed, forming asubstantially cylindrical air-tight coupling box. In the forwardcontiguous edges of the 32 is a cock in the pipe coupling 29 formed withan extending operating arm 33. 34 is a lever pivoted to a bracket 35secured to the end of the car and formed with a handle 36 at its outerend by which it can be operated. 37 isa rod pivotally connected at itsouter ends to the lever 34 and the lower pivoted section 30 of thecoupling box, whereby the said section of the coupling box can be raisedinto closed position. 38 is an arm formed integral with and extendingfrom the rod 3, Vand 39 is a link connecting the arm 3S with the end ofthe lever 34, whereby the coupling box will be opened and the train pipecoupling uncoupled, when the rod 8 is raised for uncoupling the cars.The rod 37 is also pivotally attached to the outer end of the operatingarm of the cock 32, so that when the coupling box is opened the air inthe train pipe will be shut off by the turning of the cock, and when thebox is closed, the air will be turned on by the turning of the cock. Theengaging edgesof the sections 27 and 30 of the coupling box are ofcourse provided with suitable rubber gaskets to insure air-tightconnections between them. The strength of the spring 12 and thearrangement of the lever 34 is of course such that theA pressure in thetrain pipe andcouplingbox, (which is usually forty pounds to the squareinch,) will be properly sustained and the box held in closed position.40 is a coupling section of pipe which forms the connection between thecars forthe passage of the airin the train pipe. It ispreferablyprovided with a coek 4l at its center which may be turned offwhen the car is disconnected from another car and forms theend of atrain. The preferred form of coupling section is shown in Fig. 4 of thedrawings, and consists essentially of the center rubber portion 42provided with the cock 41, and the metal heads 43 at each end. The headsconsist of an inner tube 44 securely attached to the end of the rubbertubing in any suitable manner, and formed with an annular iiange 44 nearits outer end; and the bullet-shaped cap 45 formed with the perforatedtapered forward end 45nu and the internal flange 45b at its rear endwhich ts over the tube 44 and is adapted to slide thereon. A spiralspring 4G surrounds a tube 44 and is confined between the flanges 44 and45 on the tube 44 and cap 45 respectively. The head 43 ot the couplingsection is adapted to enter the coupling box, (the tapered end servingto guide it therein) and be retained therein by the jaws of the boxengaging behind the head. The spiral spring 46 serves to allow for anymovement between the cars.

The operation of my device is as follows* The cars being in the positionshown in Fig. 1, with the air pipe coupling section secured in thecoupling box on one of the cars and the coupling` pin secured in thedrawhead of the same car, the cars are bumped together so that the yoke2O will be forced rearwardly against the action of the springs 25 whichwill allow IOO IIO

bump together, an automatic sectional coupling box having air tightconnection with the train-pipe, and means forconnectiug the coupling boxwith the pin-controlling rod, whereby the ears and air-brake pipes arecoupled siinultaneously.
